Macroscopic representation of the magnetization vector field in a magnetic substance

Lomonosov Moscow State University, Department of Physics, Leninskie Gory 1 build. 2, Moscow, 119991, Russian Federation

Expressions for the parameters of the macroscopic magnetization vector field are obtained based on a model of point magnetic moments. It is shown that the magnetization vector field consists of a vortex and a potential part. The form of the obtained expansion depends on the system of units chosen. The magnetic field of the magnetization vector and the electric field of the polarization vector are compared and shown to be equivalent. In relation to the problems discussed, the methodical aspects of teaching an ’Electricity and Magnetism’ section of a physics course are highlighted.
